Initial commit.
Wrote description of the code.
Created the Queue class.
Added a __repr__ function to Queue.
Added *.pyc to .gitignore.
Added StringStat class.  Wrote some methods.
Added the Incr and ParseChar methods to the StringStat class.  Also now import string module, and had to change variables already named string to strng.
Added place for ReturnEntropy and ReturnEntropyDensity methods to StringStat class, but haven't written anything for them yet.  Once these are written, StringStat class will be done and just have to do main code.
Wrote the ReturnEntropy and ReturnEntropyDensity functions for StringStat class.
Wrote the main code.
Separated all of the classes and functions in stringstat.py and only main code is now in entropy.py.  This way I can test the classes separately in interactive mode.
Fixed ReturnEntropy function in StringStat class:  I had thought that N=len(self.data), but that's not true because len(self.data) is just the number of keys whereas we want the sum of their values (frequencies).  Also fixed a typo in AddString where I wrote str instead of the variable name strng.
Added line to main code to actually exit if incorrect number of arguments given.
Modified main code so that you can specify nmin and nmax.
Added a future.txt to list possible future improvements (and added one possible improvement).
Changed main code to output entropy and entropy density in different columns.
Added more output information in the main code, including saturation value of the entropy.  Also added ReturnN function to StringStat class, see note in future.txt.
Fixed typo, main code works.
Fixed formatting of output columns.  Main code works.
Ran the program on an excerpt from Dive Into Python, saved results in a new directory.
